javascript - Change value of same field on multiple objects - JS -

i have object on scope, the_data, has multiple objects inside it.

one object, important_entries has list of objects inside it.

the objects inside important_entries have specific field want change - field_i_want_to_change. name of each of these objects it's id.

what want iterate on important_entries object , each object in it, change value of each field_i_want_to_change field.

could possibly give me pointers how best accomplish this? have access underscore library, if can of use.

here rough blueprint of the_data object, apologise syntax errors.

the_data : {     some_data : {},     some_data : {},     important_entries: {         xxxccc : {             field_i_want_to_change: 'some data'         },         cccfff : {             field_i_want_to_change: 'some data'         },         tttyyy : {             field_i_want_to_change: 'some data'         },     },     some_data : {},     some_data : {} } 

why don't loop through javascript object , change field?

p = the_data['important_entries']; (var key in p) {     if (p.hasownproperty(key)) {         p[key].field_i_want_to_change = 'some data';     } }
